Spina Bifida Awareness Week: Spina Bifida Occulta and tethered spinal cords

5 Min Read

Today marks the start of 2019’s Spina Bifida Awareness Week, and our charity partner Shine is bringing the “Back to the Front”, by telling people about living life with Spina Bifida and raising money for those who are affected.

I have been working with two families whose lives have been affected by a form of Spina Bifida known as spina bifida occulta, or ‘tethered spinal cord’.

What is a Spina Bifida Occulta?

It is the most common form of spina bifida, where one or more of the vertebrae do not form correctly. In most cases this does not cause a problem but in some people, the spinal cord is attached to the tissue around the spine and cannot move freely.

A tethered spinal cord mostly affects children because the tethering occurs during development in the womb. It can result from other causes too, such a spinal surgery or spinal trauma, but here we’ll focus on tethered spinal cords in children.

Problems can arise from a tethered cord as a child grows because the nerves that control parts of the body (usually the legs, bladder and bowel) are attached to tissue and become stretched. As the body grows the nerves stretch, the blood supply is reduced and damage can be caused to the part of the body that the nerves go to.

So for example, if the cord is tethered at the point where the nerves go off to the bladder, the pulling and stretching on those nerves can cause incontinence, urinary retention or bladder spasms. If the nerves going to the legs are affected, it can cause pain and weakness in the legs. The longer the problem goes on for, the worse the damage can be.

Tethered spinal cords and medical negligence

I am investigating claims for two clients at the moment and both of them were born with marks on the base of their spine. One had a hole (a dimple) and one had a large ‘strawberry mark’.

In both cases, the marks were spotted by doctors but nothing was done. If an ultrasound scan or an MRI scan had been performed, the scan would have shown that the cord was tethered and they would have been regularly reviewed by neurosurgeons and urologists. When any problems started to show as they grew, they would have had surgery to de-tether the cord.

All the guidance for doctors says that if a baby or child has a mark (which could be a dimple, a tuft of hair, a fold of skin or a strawberry mark) on the base of their spine – which is known as the sacrum – they should be scanned because there is a risk that it could be spina bifida. If a child is scanned and the cord is tethered, then it is more likely than not that the tethered cord would be identified even at birth.

Missed opportunities

In both of my cases, the marks on the base of both my clients’ spines were recognised by healthcare professionals at birth or shortly after. In both cases no scan was done, missing the opportunity for diagnosis of a tethered cord.

One of my clients was five years old and the other was eight years old when they started to show symptoms of having a tethered cord – both children started to lose the ability to control their bladder and one started to walk with one foot turning inwards.

They were both referred for a scan but by the time the tethered cord was diagnosed, the damage was already done. They both had extensive spinal surgery to detach the cord from the tissue but they are left with life-long injuries as a result of the stretching of the nerves.

An early diagnosis of a tethered spinal cord is important because it gives surgeons the opportunity to monitor development, to observe any symptoms early on and the chance to de-tether the nerves which can prevent any further deterioration.

What difference will a claim make?

A successful clinical negligence claim can only provide financial compensation, but as a firm we work with our clients to help them get answers about what went wrong, and what the future holds for them.

One parent told me “having more knowledge and a name for some of the diagnoses helps and aids in discussions with our child when they are feeling down.”

Fighting for a diagnosis

If you are worried that you or a loved one could have a tethered spinal cord, it is important to get a diagnosis as soon as possible. Speak to your GP, explain why you think there is a risk and ask for a referral for a scan.
